Nano-Implants for Energy Harvesting and Wireless Sensing


We are developing nano-devices using meta-materials that can non-invasively and remotely monitor and modulate our biological system. The requirements of the system are: 1> they should be as small as possible such that the volume displacement of tissue due to the placement of the device is minimal, 2> They should be untethered/wireless such that they can be remotely controlled. Such a device will sense the biological environment and send the information to a system outside the body in real time. The device will also have the capability to do internal analysis of the sensed data and depending on the analysis results, take further action such as electrical stimulation or drug delivery. The device will harvest energy from external applied fields for its functioning and also modulate the external fields for communicating sensed data.

The possibilities with such bioelectronic devices are endless, and we are exploring, among others, brain activity recording at a large scale with a precision of single neuron, activity recording in spinal cord and peripheral nervous system, monitoring tumor microenvironment, observing response to pathology development or external stimulus at a single cell level along with integrated functionalities such as stimulation and drug delivery.
